Recently fitted my pattern 4 into 2 on my Z1000A2 done about 200 miles
and noticed no 1 & 4 have gone a real deep blue colour, no 3 has a real yellow tinge to it and no 2 has a mild yellow tinge to it, is this indicating
that all 4 cylinders are running at different temperatures?

Hi Mikey,A happy New Year To You,Get hold of a Gunson colortune good place to start with mixture issues,get some blue away to get rid if discolour
always run up engine briefly at first and build up temp gradually to help with dis colouration, though with single skin exhausts and unleaded running hotter may be unavoidable.Cheers Paul J..

Noticeably blue means running hot and lean.
A yellowish tinge is indicative of a 'near enough' mixture, not quite so cut and dried as if you ritually abuse your right hand, (throttle, that is, keep on track everyone please), then blue hot pipes can be 'normal' as it were.
First of all, check and set valve clearances, then, as been mentioned use a colourtune to set the mixture, (after a carb clean if it's been a while or been stood any length of time), then balance the carbs and all will be good.
Re the blu-away, does that work and where does one aquire such a substance?
I've never found anything to remove the blueing and while the colour doesn't bother me personally it's an annoyance that you lose the ability to see if it occurs agsain in the future the, 650 has some blueing on the pipes from having pods on without being rejetted when I got it and subsequently running lean and hot.

You know you're getting old when you stop laughing at nasal hair trimmer adverts and start thinking, hmmmm.... you know, that looks useful!
Recently rebuilt the carbs with overhaul kits and had them
ultrasonically cleaned, but it does sound like i have a loose shim
so that be first port of call valve clearences and then balance carbs
should have done this when i done carbs but you know what its like time etc

Re; the blu-away. There has been some discussion in the past on here, i think Bill [bigmac103] has used it.
Four pipes rule, anything else is second best.

Right thought id check valve clearences today found a 3 were loose and 1 tight but with the small handful of shims was able to sort them bar one,
now with my grasp of maths
i worked out i needed a shim size of 250
which i had, but put it in and was to tight so i guess i would need a shim of 245 or 240, and am i right in thinking the club runs a shim exchange service.
